Telia Company in Voyager tests with Facebook

Telia Company subsidiary Telia Carrier recently announced a successful trial of the transponder platform Voyager on the 1,089 km Stockholm-Hamburg network route. Voyager is developed by Facebook and believed to be the first white box* transponder and routing solution in the industry. The test is an important step on the journey to disaggregate hardware from software components in networks.

The world is getting more and more connected and the internet usage is growing dramatically. To be able to meet the increasing demand and continue to stay relevant to customers, telcos needs more scalable, flexible and cost-efficient solutions to produce the services in the network infrastructure than what existing technologies offer. Telecom operators across the world are therefore seeking new and innovative solutions for the future and starting to collaborate to explore new options and drive the industry forward.

Collaboration project
This is why Telia Company joined the Telecom Infra Project (TIP) in 2016. TIP is an engineering-focused initiative that is bringing operators, infrastructure providers, system integrators, and other technology companies together to collaborate on the development of new technologies and reimagine traditional approaches to building and deploying telecom network infrastructure.

“TIP is an opportunity for us to demonstrate technology leadership by driving development in new ways in open collaboration with key players in the telco infrastructure industry. Being a New Generation Telco does not only mean that we are redefining how we are perceived by our customers in terms of our services. It also means actively seeking new ways of producing the services in an agile and cost efficient way and by that way stay relevant for our customers,” says Mauro Costa, Head of Networks Architecture and Strategy, Telia Company.

Connect the unconnected
The Voyager Field Trial is an example of how members in the Telecom Infra Project community bring their strengths together and collaborate to challenge the traditional technologies and seek new ways to deploy network infrastructure. To help make the world more open and to connect the unconnected, Facebook has contributed Voyager to the TIP-members.

The recent test shows to Telia Company that decoupled white-box transponders can be used and transported over existing long-haul DWDM - Dense Wavelength Division Multiplexing systems ** and be an important step to lowering cost of high-capacity transport. Disaggregating hardware and software components in optical networks is another important part when introducing white box transponders.

Facebook, Coriant
Telia Company experts in optical network technology supported Telia Carrier in testing the Voyager transponder in the network and will continue to work together with Facebook, Coriant and other members in the TIP to reach the goal of disaggregating hardware and software components of networks as outlined by the community.

"Eager to challenge"
“We are constantly eager to challenge the old way of working and old technologies that are not producing the maximum value for our customers. The open DWDM optical technologies tested in the Voyager Field Trial proofs that there is an alternative way to implement software defined networks with completely new economies of scale possible, not only in the international network but the networks in all our countries,” says Mauro Costa.

*White box in this case means that all components in the Voyager transponder solution are well defined in specifications and shared within the Telecom Infra Project.

**DWDM - Dense Wavelength Division Multiplexing - an optical technology used to increase bandwidth over existing fiber-optic backbone networks.
